Dopamine Release in the Medial Preoptic Area During Male Copulatory Behavior in Rats

Brain Res. 1995 Sep 18;692(1-2):66-70. doi: 10.1016/0006-8993(95)00656-b.

Abstract

In vivo microdialysis was employed to measure the extracellular concentrations of dopamine (DA) in the medial preoptic area (MPOA) of rats during male sexual activity to look for a correlation with sexual activity. During copulation, the concentration of DA in the MPOA was significantly increased. A significant difference was detected in changes of DA between copulators and non-copulators. These findings were consistent with the assertion that DA neuron activity in the MPOA facilities male copulatory behavior.
